The problem is that the PCM is grounded by the firewall. I'm sure you've fixed this is an old post but if anyone else reads this. The PCM is grounded by the firewall. I found continuity with an ohm reader. I say manufacture defect. if anyone still wants to know how to remedy this stalling, electrical problem, I will be glad to share my research and answer. Original owner of a 1996 Jeep Grand Cherokee Limited. Still running after all that.... Saved a lot of $$$ working on it myself.

I have a 2003 Jeep GC Laredo and well we can get it to start but after driving about 5 blocks it either tries to die or does and then it goes down hill from that we were told fuel pump but i dont think thats it cause we can get it to idle as long as we dont touch the gas or put it in gear. PLEASE SEND ME THE INFO thank you

I have replaced the crank and cam sensor but still nothing. Not getting fire from the coil but it tested fine. Cant just put a pcm in unless i have a good idea thats it. Ive ran all the tests i know to run and need help. It used to make me wait till the pump would pressure up and when it would finally pressure up the check engine light would flutter with it. The relay box would also make the clicking noise along with the fuel pump. It all took about a min for the pump to ingage. Once the pump ingaged and the relays quit clicking it would start and run good. Now nothing ..#32 of 37 Re: AAAAAHHHHHHH [melbistylz] by desert_rogue

I have a 2007 Cherokee SRT8 and recently it has started to die without warning or reason. Dealer says the PCM is defective but am not so sure. it seems to be worse when it gets hot and also when the dealer "tested" it by giving it a good hard whack with the palm of his hand with the car running it stopped.
I believe the PCM will be rated for the extreme temperatures under the hood so I am inclined to think it is a bad contact. Would appreciate to have some info on what you found before I spend over $1,000 on a new PCM which might not cure the issues.
The only other items I thought bout were the crankshaft position sensors and the camshaft position sensors.
Any help you can give would be great. it does not suit being a yard ornament, it is meant to run.
